Specification forming part of Vlhettersi Patent No. 87,299, daredFebruary 23, 1869.

To all whom 'it may concern:

Be it known that I, JOSEPH EMANUEL SOHWIPPEL, of St. Joseph, in thecounty of Buchanan, and in the State of Missouri, have invented certainnew and useful Improvements in Machines for Generating Gas; and I dohereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,and to the letters of reference marked thereon.

The nature of my invention consists in the construction and generalarrangement of a i Fig. 2 is a side view, of the machine, the front sidebeing removed.

A represents a hollow cylinder, made of copper or other suitablematerial, through the center of which a shaft, B, passes. On this shaft,inside of the cylinder A, is placed a wheel, C, which is constructed onthe principle ofthe long-known cagnardelle,or French blowing-wheel, andis nothing more than a combination of a screw and a wheel, as seen inthe drawings. A- due or pipe, D, allows the air to pass into theinterior of the screwwheel, which,by its rotation in the gasolinecontained in the generator A, causes a steady current or draft of air toplay in the interior of the machine and press toward the orifice of theburner or burners, which are or may be attached to the pipes connectedwith the generator. l I

So far, the screw-wheel C acts as a common bellows, blowing air into thegenerator A.

vTo combine its action as a blower with the qualification of anevaporator said screw-wheel is, on its outer surface, provided with atrimming, E, of common fringe of raw silk or other suitable material,said fringe being wound or attached closely around the wheel, so as toform a circular brush.

A sheet of copper or tin, F, (the protector,) is .fastened in ahalf-circle to the inside of the cylinder A, so as to form the half of acylinder within the former, but leaving a small space between them.secured -to the upper inner side of the generator, and is, on its lowerside, also provided with fringe, G, against which the combined brushscrew-wheel G is gently rubbing Without im'- pedin g its motion.provided with small holes, a a, to let the gas pass,-but to avoid anycontact of the frame with the fluid'.

From the top of the generator A, a. pipe, H, leads to the burner. Theopening b in the top of the generator, which is closed by ascrewstopper, c, and screw-capot, is for the purpose of admitting thegasoline or paraftne-oil, from which the gas is generated, into thecylinder A. The iiuid is admitted until it reaches the gage e on therear side of the generator, when the opening b is securely closed.

When, now, the shaft-B is turned the abovedescribed brush screw-wheel Cdips into the iuid, and with the fringe carries it up and moistens thefringe of the concave protector F, and, with theaidrof the constantcurrent of air passing and blowing through said fringe trimming, thegasoline evaporates into gas, and is forced in that form toward theburner.

The end of the shaft B passes through the end of the cylinder A, and acrank may be applied to the same, so as to turn the wheel C.

The machine as represented in the drawings, and which I denominateSchwippels Universal Luminator, is applicable to lampposts, as a fewrevolutions only of the machine are sufcient to generate gas enough forthe time that street-lamps generally are lighted.

To light houses, public halls, &c., where number of burners are used,the machine will of course be made on a larger scale, and then the wheelC may be turned by a weight, clockwork, or any other suitable means. Thetube fat the bottom of the generator is for the` purpose of emptying theremaining fluid when so desired. Around one end of the shaft B is placeda stuffing-box, g, by means of which more air can be admitted to thegenerator, if deemed necessary.

Having thus fully described my invention,

This half-cylinder F is The protector F is further air-pipe D, allsubstantially as and for the purposes herein set orth.

In testimony that I claim the foregoing I have hereunto set my hand this2d day of JOSEPH E. SOHWIPPEL.

Letters Patent, is-

1. The arrangement of the generator A,

having inlet b, outlet f, gage e, `and pipe H,
